Method and device for controlling a steering assistance system of a steering device of a single-track motor vehicle

Abstract

A method for controlling a steering assistance system of a steering device of a single-track motor vehicle. Current vehicle operating parameters are continuously recorded by way of a sensor system; and, subsequently the current vehicle operating parameters are compared with limit values stored in a control unit of the single-track motor vehicle in order to determine a lifting front wheel of the single-track motor vehicle for the corresponding vehicle operating parameters by way of the control unit. Then, if at least one of the limit values is reached and/or exceeded, the steering assistance system is controlled by way of the control unit in such a way that the steering device is aligned to a predefined steering angle of the steering device, at which steering angle the steering device is prevented from wobbling.

The invention claimed is: 
     
         1 . A method for controlling a steering assistance system of a steering device of a single-track motor vehicle, the method comprising:
 continuously detecting current vehicle operating parameters by way of a sensor system,   comparing the current vehicle operating parameters to limiting values stored in a control unit of the single-track motor vehicle to determine a lifting front wheel of the single-track motor vehicle for the corresponding vehicle operating parameters by way of the control unit,   wherein if at least one of the limiting values is reached and/or exceeded, the method further comprises controlling the steering assistance system by way of the control unit such that the steering device is aligned at a predetermined steering angle of the steering device, at which a kickback of the steering device is prevented.   
     
     
         2 . The method according to  claim 1 , wherein the control unit controls during the control of the steering assistance system by way of a steering actuator of the steering assistance system. 
     
     
         3 . The method according to  claim 1 , wherein the control unit controls the steering angle of the steering device into a middle position with respect to a respective maximum steering angle or into a current direction of travel of the single-track motor vehicle during the control. 
     
     
         4 . The method according to  claim 1 , wherein the sensor system comprises a steering angle sensor and a steering angle of the steering device is ascertained during the continuous recording. 
     
     
         5 . The method according to  claim 1 , wherein the sensor system comprises a rotation rate sensor and a rotational velocity of the single-track motor vehicle is ascertained during the continuous recording. 
     
     
         6 . The method according to  claim 1 , wherein the sensor system comprises an inclination sensor and an angle of inclination of the single-track motor vehicle is ascertained during the continuous recording. 
     
     
         7 . The method according to  claim 1 , wherein the sensor system comprises a spring deflection sensor and a deflection of the steering device is ascertained during the continuous recording. 
     
     
         8 . The method according to  claim 1 , wherein the sensor system comprises an acceleration sensor and an acceleration of the single-track motor vehicle, in the vertical direction, is ascertained during the continuous recording. 
     
     
         9 . The method according to  claim 1 , wherein the control unit outputs a warning signal by way of a display device of the single-track vehicle if at least one of the limiting values is reached and/or exceeded. 
     
     
         10 . The method according to  claim 1 , wherein the sensor system comprises a steering torque sensor and a steering torque of the steering device by a driver is ascertained during the continuous recording, wherein the control unit factors in the steering torque in the control of the steering device. 
     
     
         11 . A single-track motor vehicle comprising:
 a device for controlling a steering assistance system of a steering device of the single-track motor vehicle according to the method of  claim 1 , wherein the steering assistance system is controllable by way of the control unit such that the steering device is aligned at a predetermined steering angle of the steering device, at which a kickback of the steering device is preventable.
